How does radius of an atom affect melting point?

Answer 1

The Bohr model, introduced in 1913 by Niels Bohr was simply the model of the atomic structure; this included the small positively charged nucleus which included the neutrons and protons at the centre and the negatively charged electrons rotating around the nucleus in certain specific orbits by its electromagnetic energy in a circular orbit, similar to the solar system, but with electrostatic forces providing attraction, rather then gravity. In a neutral atom the number of electrons = the number of protons. The arrangement of an atom's energy orbits depends on the number of protons and neutrons in the nucleus and the number of electrons orbiting the nucleus.

Answer 2

The radius of an atom affects the melting point because as the atom size increases, the atoms are further apart and have weaker intermolecular forces, leading to a lower melting point. Conversely, smaller atoms with closer packing and stronger intermolecular forces have higher melting points.

Answer 3

Atom Radius does not affect the melting point directly

The larger an atoms radius the larger the nucleus and therefore the larger the nuclear charge. Increased nuclear charge leads to an increased strength of van der waal's forces between the molecules which results in a higher melting point.

The opposite occurs when the atoms radius is smaller

Answer 4

It's an inverse relationship. As you go down Group 1, the Alkali Metals, atomic radius increases and melting point decreases.

Answer 5

Supposed melting poin of francium: 22 0C

Supposed boiling point of francium: 650 0C

Answer 6

The melting point decreases and the atomic radius increases as you go down the group.

Answer 7

Excepting halogens a relationship between atomic radius and melting point doesn't exist.

Answer 8

i dont no im trying to fint out too

Answer 9

A general relation doesn't exist.

Answer 10

Generally a relation doesn't exist.
